Step 1: Choose Containers
Select two pots that are at least 10 inches in diameter and suit any space handy for picking. Use multipurpose or soil-based compost, and ensure the plants are situated on a patio or balcony with a moderate amount of shade.
Step 2: Go Shopping
Buy the following plants: one garden mint (spearmint), one Petunia ‘Phantom’, one viola, one Moroccan mint, one basil mint and one pineapple mint.
Step 3: Plant Mints
Mints are best planted in spring, but petunias are killed by frost, so plant this display in late spring or early summer. Ensure the containers have drainage holes; the tall chimney pot used here has a plastic pot slotted into it. Fill the base of each pot with a layer of compost, and arrange the plants in their best positions in the containers. Then water them well, knock them from their pots, and plant up. Firm the compost and water in well. Keep the mints moist throughout the growing season, cut back old stems when they die down in winter and apply an all-purpose granular fertilizer in spring.
Squeeze extra growing space into small plots and onto patios with a hanging basket of tomatoes and herbs.
